Thank you for purchasing the LSI MegaRAID LiON (lithium

ion) intelligent Battery Backup Unit 01 (LSIiBBU01). The

LSIiBBU01 is designed for use on MegaRAID SAS RAID

controllers. It protects the integrity of the cached data on a

MegaRAID controller for up to 72 hours in the event of a

complete AC power failure or a brief power outage.

LSI provides a family of MegaRAID intelligent battery backup

units (iBBUs) for use with its high-performance MegaRAID

RAID controllers. The LSI MegaRAID iBBUs provide an

inexpensive alternative to using an uninterruptible power

supply and a second level of fault tolerance when used in

conjunction with an uninterruptible power supply.

This quick installation guide explains how to install the

MegaRAID LSIiBBU01 for use with the following controllers:

• MegaRAID SAS 8308ELP

• MegaRAID SAS 8344ELP

• MegaRAID SAS 84016E

• MegaRAID SATA 300-8ELP

• MegaRAID SATA 300-8XLP

Please take a few minutes to read this Quick Installation

Guide before you install the iBBU. For more information

about the LSIiBBU01, refer to the Intelligent Battery Backup

Units for 1078-based MegaRAID Products User’s Guide on

your MegaRAID Universal Software Suite CD.

Overview of the Intelligent Battery

Backup Unit

An intelligent BBU has built-in functionality to charge the

battery pack automatically and to communicate battery

status information such as voltage, temperature, and current,

to the host computer system.

The LSIiBBU01 does not connect directly to the MegaRAID

controllers. Instead, it uses the supplied 20-pin, 12-inch

cable to connect remotely to a controller. The LSIiBBU01

must be mounted inside the chassis within 10 inches of the

RAID controller.

Because server and workstation chassis vary from vendor to

vendor, there is no standard mounting option that is

compatible with the various system configurations. The

LSIiBBU01 battery kit contains only the battery and the

cable, allowing VAR’s and chassis manufacturers to

customize the location of the remote battery to provide the

most flexibility within various environments.

The LSIiBBU01 combines a battery pack with a

daughtercard. Figure 1 shows the top view and the bottom

view of the LSIiBBU01, the M2.50-0.45 x 5mm screws, and

the 6mm standoffs. (The “top” side is the side that you can

see after you install the iBBU on the RAID controller.)

Note

: The LSI part number for the daughtercard is

25126.

Installing the LSIiBBU01 and Connecting

it Remotely to a MegaRAID RAID

Controller

This section documents how to install the LSIiBBU01 and

connect it remotely to the MegaRAID SAS 8344ELP RAID

controller. You can connect the LSIiBBU01 to the other RAID

controllers in a similar manner.

Perform the following steps to install the LSIiBBU01 and

connect it remotely to the SAS 8344ELP RAID controller.

Step 1 Ground yourself, and remove the LSIiBBU01 from

the package.

Step 2 Use the three Phillips-head screws that are

provided to secure the LSIiBBU01 to the
